Successive approximation analog-to-digital converter with nonlinearity compensation
Successive-approximation-register (SAR) analog-to-digital conversion technique continues to be one of the most popular analog-to-digital conversion techniques, due to their versatility, which allows providing high resolution output or high conversion rates. In addition, SAR analog-to-digital converters (ADC) have a modest circuit complexity that results in low-power dissipation. A SAR ADC is, typically, composed of a single comparator, a bank of capacitors and switches, in addition to, a control digital logic. However, the comparator input capacitance is input-signal dependent, and hence introduces non-linearity to the transfer characteristics of the ADC. A simple technique is devised to significantly reduce this non-linearity, by pre-distorting the sampled-and-held input signal using the same comparator input capacitance. |
